Product Decisions This Supports
- Build vs. buy on input-boundary validation. This package informs the "assert at the edge" decision: whether to add a small runtime type-assertion primitive, or rely on PHP 8 typed properties, union types,
declare(strict_types=1), and static analysis (PHPStan/Psalm) instead. For most modern Laravel codebases the answer is the latter.
- Legacy hardening roadmap. If any service still runs PHP 7.x, or has untyped boundaries (decoded JSON, config arrays, third-party SDK responses, job payloads), a lightweight assert helper closes a real gap that static analysis cannot reach.
- Dependency governance / TCO policy. A concrete data point for whether tiny single-maintainer utility libraries belong in the dependency policy at all — every added package carries audit, upgrade, and CVE-watch cost regardless of size.
- Use cases it can serve if adopted: validating decoded JSON before hydration, guarding array shapes in service providers/commands, and defensive checks in queued jobs where type errors otherwise surface as opaque 500s far from the cause.
- Not a differentiator. Nothing here touches product features or roadmap; it is purely an engineering-risk and code-health decision. Treat it as an internal standards call, not a product bet.
When to Consider This Package
Adopt only if:
- You are on PHP < 8.0 (or a mixed-version fleet) where native types and strict typing are not uniformly available.
- The team has no static analysis in CI — in which case a runtime assert is the cheaper substitute for PHPStan/Psalm.
- You need a handful of assertions and are willing to vendor or fork the code and own it internally.
Look elsewhere if: any of the following hold, which is the common case:
- PHP 8.1+ — native types, enums, and
readonly already cover the assertion surface; PHPStan/Psalm at max level catch the rest at build time.
- You want a maintained, battle-tested alternative —
webmozart/assert (very large install base, active), beberlei/assert, Symfony Validator, or Laravel's own Validator / Illuminate\Validation.
- You need structured, aggregatable errors for forms or API responses — exception-throwing assertions are the wrong shape; use a validator.
- You need Laravel integration — this package ships no service provider, facade, or config, so expect zero framework ergonomics.
- Risk signals dominate: 1 GitHub star, 0 dependents, last release November 2022, no community. That means no security-patch path, no demonstrated PHP 8.x compatibility guarantee, and high abandonment risk. For a package whose entire value is ~100–200 lines of trivial code, the dependency is more expensive than the capability.
How to Pitch It (Stakeholders)
To executives: This is a tiny, MIT-licensed utility with no cost and no strategic value. Recommendation: do not adopt it as a runtime dependency. The capability it provides is a few hundred lines we can own outright, and taking the dependency adds a supply-chain and maintenance liability with no offsetting benefit — one maintainer, one star, no releases since 2022, and no upgrade path if it breaks on a future PHP version. The decision is about risk, not budget; there is no financial impact either way.
To engineering: Type assertions at trust boundaries are a legitimate pattern, but this package is the wrong vehicle. It has no Laravel integration, no static analysis story, no community, and no release in over two years. Standardize on native PHP 8 types plus PHPStan/Psalm in CI; where runtime assertions are genuinely needed (untrusted JSON, config shapes), use webmozart/assert or an internal Assert helper. Fork the idea, not the package. If a team insists on shipping it, pin the version, vendor the source into our repo, and register it on the owned-code list so it gets audited like first-party code.
